Full Moon Festival - S1.E12

Hajime has suggested that during the joint live between Gravi and Procella, all 12 members sing a new song everyone can enjoy. Even though all the members and the managers agree the idea, they would need to get Tsukino Talent Production's President Tsukino Mikoto's approval to be able to turn Hajime's idea into a reality, as well as have him write the song, as he has worked on all their units songs up to that point. But it looks like asking the President such a thing is difficult, as he is currently carrying heavy pressure do to work...?

Will Gravi and Procella be able to show the fans who've waiting for live the new bonds, the new song they've formed...!?
